stumpy_png

Written entirely in Crystal without external bindings, ensuring portability and avoiding reliance on C libraries, except for zlib which is a minimal system dependency.

Supports all standard PNG features including color types, filter methods, interlacing, and 8/16-bit depths, as detailed in the README's feature checklist.

Offers straightforward read/write methods with configurable parameters like bit depth and color type, making basic image operations simple to implement.

Seamlessly uses Canvas and RGBA types from stumpy_core, providing a consistent interface for pixel-level manipulation across the stumpy ecosystem.
